A database management system stores, organizes and manages a large amount of information within a single software application. A database server is the key to solving the problems of information management.  It is important because it manages data efficiently and allows users to perform multiple tasks with ease. More to that, these DMSs are critical for businesses and organizations because they provide a highly efficient method for handling multiple types of data.

In order to make the most out of these Database systems, users can categorize and structure the data in a way that best suits the needs of the company or organization. Data can be entered into the system and accessed on a routine basis by assigned users. Each user may have an assigned password to gain access to their part of the system. Multiple users can use the system at the same time in different ways.

While MySQL and Oracle are Relational Database Management Systems, MongoDB and Hadoop are NoSQL databases.


An Oracle database is a collection of data treated as a unit. Oracle is the only database which is designed for enterprise grid computing – the most flexible and cost effective solution to handle information and applications. It is one of the most widely-used RDBMS, built on a relational database framework. Enterprise grid computing creates large pools of industry-standard, modular storage and servers. With this architecture, each new system can be rapidly provisioned from the pool of components. There is no need for peak workloads, because capacity can be easily added or reallocated from the resource pools as needed.

Advantages of using Oracle

  • Oracle offers robust functionalities, making it perfect for practically all corporations that have huge amounts of data to store and access.
  • Oracle is a database that delivers excellent performance when challenged with demanding tasks, making it highly reliable.
  • Oracle databases incorporate Flashback technology, which is a significant advantage.
  • It also features four important features i.e. atomicity, consistency, isolation and durability.
  • This certainly makes Oracle even more robust by providing a reliable and competent database system.

NoSQL is a portable and fast RDBMS with zero arbitrary limits which covers diverse database technologies. It was developed in response to the increasing volume of data stored about users, products and objects. NoSQL determines the frequency in which data should be accessed in addition to its performance and processing needs. NoSQL is used for its performance powered with high availability, and provides robust query language and simple scalability.

Advantages of using NoSQL

  • NoSQL’s Elastic Scaling is precisely what makes it so well-suited for big data.
  • A NoSQL database is considerably less restricted than an SQL database, making it more flexible.
  • NoSQL databases tend more often than not to be considerably less complex and considerably simpler to deploy than their relational cousins.
  • The servers utilized in a NoSQL implementation are typically cheap, low-grade commodity devices, as opposed to the oft-expensive servers and storage systems required in relational databases.
  • For NoSQL, the cloud’s the limit as NoSQL meshes naturally with cloud computing.

MySQL is an open source SQL database developed by Swedish company MySQL AB. It supports various platforms including, Microsoft Windows, Linux, UNIX and Mac OS. It comes with fast, multi-threaded, multi-user and rich SQL database server.

Advantages of using MySQL

MySQL is a widely used open source database. MySQL is the backend database of most of the websites. The advantages of MySQL are as follows:

  • MySQL being an open source database system, it can be downloaded and used by the developer for free.
  • MySQL is robust and it provides excellent performance due to usage of MyISAM.
  • MySQL occupies very less disk space.
  • MySQL can be easily installed in all major operating systems like Microsoft Windows, Linux, UNIX.
  • MySQL can be easily learnt using the tutorials that are available on internet.
  • Though MySQL is open source, it offers most of the features provided by Oracle and other leading databases.
  • MySQL is best suited for small and medium applications.
  • Since MySQL is acquired by Sun, Java is soon expected to include enhanced MySQL connectivity.
